We spent a lot of time trying to learn if the Tuesday press conference that Verizon is holding is actually going to be an announcement that they have secured a deal for the first CDMA/EVDO iPhone. What we know is that the AT&T exclusive is ending and Apple has been doing a lot of talking with Verizon.

Sources and Analysts we have spoken with over the weekend feel that Tuesday Verizon will officially announce that the iPhone is coming. It is expected that Steve Jobs will make an appearance at the Verizon event in person or by video, according to the whispers that we have heard.

It is tough to predict how much of an impact this will have on AT&T, but analysts we have spoken with over the weekend suggest that the impact could be much greater than everyone might think. Numbers as high as 5 or 6 million subscribers might jump from AT&T to Verizon if they have the chance, according to our sources. The good news for Apple is that they are going to sell a lot of phones right out of the gate by adding Verizon as a carrier in the US.

The biggest impact, however, might be that of the Android platform phones, as the addition of the iPhone on Verizon might sway potential customers in another direction and could have a bigger impact than expected.

The critical news about the Verizon iPhone is about what it will not offer, which is LTE support. As with the first generation iPhone on AT&T, the Verizon iPhone will not support the new latest 4G network from Verizon. It is expected that the Verizon iPhone will get LTE support down the road, but it could be 2012 or later before Verizon customers actually get it.

Meanwhile, the next rumored refresh of the AT&T iPhone is said to support AT&T’s new 4G intuitive, which isn’t LTE, but it will offer higher network speed and performance; however, users will have to have the new model to use it. It is rumored that AT&T will get an iPhone with LTE support before Verizon, which might be ironic, as Verizon is much further along on their LTE build out than AT&T is.

Sources are confirming that the iPhone is finally coming to Verizon early next year. According to what we have been hearing, the deal is done and Apple is already making plans to crank up production of the new CDMA/EVDO version of the iPhone for the launch. This seems to go along with the news that we told you about previously that Apple had already cut a deal for the chips to be used in the new version.

If this does actually come to pass this time around, it will mean an end to AT&T’s exclusive that they have enjoyed on the iPhone since its launch in the U.S. The good news for Apple is that they will be better able to go to battle with the number of Android models being released by offering a choice of two carriers from which to get the iPhone.

Of course, neither Apple nor Verizon are talking about the deal, but it is expected that we will hear more just after the first of the year. The loser in all of this is expected to be AT&T, who could stand to lose a number of subscribers that are expected to jump ship once the iPhone is available on Verizon.

The official launch for the Microsoft Windows Phone 7 is coming to North America in October. Surprisingly, it does appear that AT&T will launch their Windows Phone 7 offerings first on October 11th at an event in the morning, while T-Mobile will launch their Windows Phone 7 models later in the afternoon.

The news does seem to confirm the fact that at least to start with there will be no CDMA/EVDO Windows Phone 7 models to start with; and Verizon and Sprint are sitting this one out. While rumors of Windows Phone 7 CDMA/EVDO models for next year continue, it is believed that both carriers will be watching the performance of the Windows Phone 7 models on AT&T and T-Mobile before committing to them.

Microsoft has very high hopes for the Windows Phone 7 and it is hoping that it can recapture at least some of the market space that it has lost in this area. Early buzz seems to be positive over the new fusion of an interface that can be described as a little bit Xbox, with some Zune, and a splash of Kin thrown in. While it doesn’t sound like it would work well, the early buzz is very positive which could be a good sign for Microsoft.
